Practical difficulties

Products going to different warehouses Loss of contact with readers

Loss of power to readers Loss of GSM connectivity Antenna failures

Belt deflection likely to interfere with antennas encircling belts Harsh, dusty environments

Experiments in these organizational and mechanically harsh

environments need to be foolproof
